Beach marks on a polystyrene fracture surface
The fracture surfaces are generally very sharp and angular, indicating fast, brittle fracture with little ductile tearing. 'Beach marks', can be seen where the fracture has grown at a speed comparable to the speed of sound in the material. This results in periodic, momentary arrests in the crack propagation and periodic ridges in the fracture surface as it advances. There is also evidence of the fracture surface branching onto different planes as it progresses.

Lecture 14: Innovation, Spin-out Companies and Nanotechnology
Professor Peter Dobson on "Innovation, Spin-out Companies and Nanotechnology". Innovation is what happens between the invention stage and the generation of revenue arising from the invention. For a knowledge economy such as in the UK, it is imperative that we can optimize innovation. At Begbroke we have been trying to understand the dynamics and barriers to innovation by creating a unique Science Park where high technology spin-off companies work on the same site as interdisciplinary University

Patient Race/Ethnicity and Quality of Patient–Physician Communication During Medical Visits
Objectives. We examined the association between patient race/ethnicity and patient–physician communication during medical visits. Methods. We used audiotape and questionnaire data collected in 1998 and 2002 to determine whether the quality of medical-visit communication differs among African American versus White patients. We analyzed data from 458 African American and White patients who visited 61 physicians in the Baltimore, Md–Washington, DC–Northern Virginia metropolitan area. Outcome

Nanoscience
The Kavli Institute of Nanoscience at Delft University of Technology studies new physics and exploits novel principles in nanostructured devices with a new functionality. The nanostructures vary from superconductors to biopolymers and are obtained from nature or fabricated with bottom-up methods (starting with atoms or molecules) or top-down techniques (such as electron-beam lithography). The Institute consists of several research groups and a nanofabrication cleanroom facility. With a staff of

Immunization Hesitancy: A Rising Tide that Challenges the Public Health
Societal support for traditional childhood immunization is changing. Increasingly, parents are renegotiating recommended immunization schedules with pediatricians. Marcuse, also associate medical director at Seattle Children's Hospital, discusses this hesitancy and the potential consequences for disease prevention. In this videotaped lecture, he also addresses balancing parental rights with protecting public health. This lecture was part of the Howard A. Schneiderman Memorial Bioethics Lecture S

Towards an organisational model of ‘interface’ university structure as a means of serving Lifelong
The paper conceptualises on the experiences of the Centre of Information Society Technologies (CIST), Sofia University, Bulgaria, in serving the learning and training needs of non-university audiences who fall in situations that can be described as lifelong learning-determined. In developing this conceptualisation we use the research findings and policy agendas in two distinct areas – Lifelong Learning, and Higher Education Systems. More specifically we explore the organisational and management

Modélisation de profils d'élèves à partir de traces de résolution de problèmes
La modélisation automatique des connaissances de l’apprenant est nécessaire dès lors que l’on cherche à accompagner un apprentissage dans le cadre des EIAH. Dans ce rapport, nous présentons un travail en cours dans lequel des techniques de classification automatique permettent d’engendrer des modèles d’élèves interprétables par un enseignant ou un didacticien et utilisables éventuellement par un « tuteur » automatique. L’approche proposée a été appliquée au domaine de la ré

Design and architecture of an online system for Vocational Education and Training
E-learning and tele-training have been evolved over time from a newborn trend for complementing the learning process to a major form of education and training for supporting mainly geographically scattered users. Learning and training, can be applied to a wide variety of fields and areas, each of which is accompanied by some special characteristics related to the field of learning/training, to the tools needed for the realization of the training process as well as to the familiarization of the t

Efficient object based streaming framework for web-based education
An efficient moving object extraction algorithm suitable for real-time content-based multimedia streaming systems is proposed in this paper. A Motion Vector (MV) based object extraction is used to dynamically detect the objects. To utilize the bandwidth efficiently, the important object can be real time detected, encoded, and transmitted with higher quality and higher frame rate than those of background. In order to meet the real-time requirement, no computationally intensive operation is includ

The defining characteristics of intelligent tutoring systems research: ITSs care, precisely
his paper argues that, despite the changes in philosophies and techniques that have occurred since ITS research began, there are continuous threads running through this research which define its essential and distinctive nature. In particular, ITSs are computer-based learning systems which attempt to adapt to the needs of learners and are therefore the only such systems which attempt to 'care' about learners in that sense. Also, ITS research is the only part of the general IT and education fie

Making the History of 1989: The Fall of Communism in Eastern Europe
Making the History of 1989 materials were developed because teachers and their students have little access to vivid historical documents in English that convey the epochal events of 1989. Project materials utilize recent advances in our understanding of how historical learning takes place, including complex interaction with sources, recursive reading, and skills used by historians. The site has three key features: a substantial collection of high quality primary sources; a set of multimedia int
